+% \begin{abstract}
+%   The \EGP{} package allows to encapsulate \GP{} commands in \LaTeX{}
+%   sources.  This is very useful for keeping illustrations in sync
+%   with the text. It also frees the user from inventing descriptive
+%   names for PostScript files. Additionally the package provides commands that
+%   enable the user to let \GP{} do calculations and insert the result values
+%   into the generated output.

+% \section{Introduction}
+% \label{sec:intro}
+%
+% When adding illustrations to documents, one faces two bookkeeping
+% problems:
+% \begin{enumerate}
+%   \item How to encourage oneself to keep the illustrations in sync
+%     with the text, when the document is updated?
+%   \item How to make sure that the illustrations appear on the right
+%     spot? 
+% \end{enumerate}
+% For both problems, the best solution is to encapsulate the figures
+% in the \LaTeX{} source:
+% \begin{enumerate}
+%   \item It is much easier to remember to update an illustration if
+%     one doesn't have to switch files in the editor.
+%   \item One does not have to invent illustrative filenames, if
+%     the computer keeps track of them.
+% \end{enumerate}
+% This concept of integrating the image generating commands into the \LaTeX{}
+% source was implemented for \MF{} by Thorsten
+% Ohl\footnote{e-mail:\texttt{Thorsten.Ohl@Physik.TU-Darmstadt.de}} in the
+% \EMP-package.
+% The \EGP{} package now allows the encapsulation of \GP~\cite{GP} into
+% \LaTeX~\cite{LaTeX-Graphics-Companion,LaTeX,LaTeX-Companion}. Although \GP{}
+% provides several output formats that are suitable for the inclusion into
+% \LaTeX{} the \EGP{} package is only intended for use with the Postscript
+% terminal of \GP{} so far.
+%
+% In addition to the image inclusion commands \EGP{} provides the user with
+% commands to let \GP{} do calculations and include the results into the
+% document. Unfortunately these features are implemented with the UN*X text utils
+% and so they are only usable if these are installed on the system. Since the
+% names for the PostScript and the result values files are built by appending
+% the figure/calculation number and a three letter extension (|.eps| or |.val|)
+% to |\jobname| the user has to choose a |\jobname| that is short enough so
+% that the generated filenames fit into the conventions of certain operating
+% systems. 
+%
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \section{Usage}
+%
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \subsection{Options}
+% \label{sec:options}
+% 
+% \DescribeMacro{Options}
+% Besides the options of the |graphicx| package the option |german| is
+% recognized by the \EGP{} package.
+%
+% If |german| is specified the calculated values and the tic labels of the
+% diagrams are changed to show a `,' as decimal point character. The default is
+% a `.'. This feature is also implemented with UN*X text utils and is only
+% available if they are installed on the system.
+%
+% \subsection{Commands and Environments}
+% \label{sec:commands}
+%
+% \subsubsection{Miscellaneous}
+% \label{sec:misc}
+%
+% \DescribeEnv{egpfile}
+% All descriptions that should go into one \GP{} file are placed
+% inside a |egpfile| environment which takes the name of the \GP{}
+% file as an optional argument:
+% \begin{quote}
+% \begin{flushleft}
+%   |\begin{egpfile}[|\meta{\GP-file}|]|\\
+%   \qquad\ldots\\
+%   |\end{egpfile}|
+% \end{flushleft}
+% \end{quote}
+% The default \GP-filename is |\jobname.gp|.
+%
+% \DescribeEnv{egpcmds}
+% \DescribeMacro{\egpwrite}
+% Write \GP{} commands to the current file outside of a figure. 
+% The |\egpwrite| command is intended for short one line commands.
+% \begin{quote}
+% \begin{flushleft}
+%   |\begin{egpcmds}|\\
+%     \qquad\meta{\GP-commands}\\
+%   |\end{egpcmds}|
+% \end{flushleft}
+% \end{quote}
+%
+% \DescribeMacro{\egpprelude}
+% \DescribeMacro{\egpaddtoprelude}
+% Define and add to the set of commands that are prepended to the top of
+% every \GP{} file. It is intended for the global definition of variables
+% or functions.
+%
+% The default is empty.
+%
+% \subsubsection{Figures}
+% \label{sec:images}
+%
+% \DescribeEnv{egp}
+% \DescribeEnv{egpx}
+% \DescribeEnv{egpdef}
+% The |egp| as the |egpx| environment contains the description of a single
+% figure that will be placed at the location of the environment.
+% The |egpdef| environment only defines a figure but does not include it into
+% the document. This is useful, because these environments use the
+% |verbatim| package and can therefore \emph{not} be used as an
+% argument to other macros. The \meta{name} that is assigned to the figure is
+% used for later inclusion with the |\egpuse{|\meta{name}|}| command.
+% For the |egp| and |egpx| environment the assignment of the \meta{name} is
+% optional.
+% The required argument of the |egpx| environment accepts any set of keys
+% accepted by the |\includegraphics| command of the |graphicx| package.
+% \begin{quote}
+% \begin{flushleft}
+%   |\begin{egp}[|\meta{name}|]|\\
+%     \qquad\meta{\GP-commands}\\
+%   |\end{egp}|
+% \end{flushleft}
+% \end{quote}
+% \begin{quote}
+% \begin{flushleft}
+%   |\begin{egpx}[|\meta{name}|]{|\meta{key val list}|}|\\
+%     \qquad\meta{\GP-commands}\\
+%   |\end{egpx}|
+% \end{flushleft}
+% \end{quote}
+% \begin{quote}
+% \begin{flushleft}
+%   |\begin{egpdef}{|\meta{name}|}|\\
+%     \qquad\meta{\GP-commands}\\
+%   |\end{egpdef}|
+% \end{flushleft}
+% \end{quote}
+%
+% \DescribeMacro{\egpuse}
+% Reuse a previously defined figure.
+% The optional argument of the |\egpuse| command accepts any set of the keys
+% that is accepted by the |\includegraphics| command of the |graphicx| package.
+% \begin{quote}
+% \begin{flushleft}
+%   |\egpuse[|\meta{key val list}|]{|\meta{name}|}|\\
+% \end{flushleft}
+% \end{quote}
+%
+% \DescribeMacro{\egpfigprelude}
+% \DescribeMacro{\egpaddtofigprelude}
+% Define and add to a \GP{} prelude that is prepended to the output of
+% every |egp|, |egpx| or |egpdef| environment. 
+% The default is:
+% \begin{quote}
+% \qquad{}|set terminal postscript eps monochrome dashed "Helvetica" 17|
+% \end{quote}
+% In fact this is the command where the terminal for the \GP{}-|plot| command
+% is set. So the user has to take care that (Encapsulated) PostScript output is
+% generated.
+%
+% \DescribeMacro{\egpfigepilog}
+% \DescribeMacro{\egpaddtofigepilog}
+% Define and add to a \GP{} epilog that is appended to the output of
+% every |egp|, |egpx| or |egpdef| environment. 
+% This command can be used for e.g. |replot|ting the figure to the screen or
+% |reset|ing to the defaults after every figure.
+%
+% The default is:
+% \begin{quote}
+% \qquad{}|reset|
+% \end{quote}
+% 
+%
+% \subsubsection{Calculating}
+% \label{sec:calculations}
+%
+% In addition to the commands and environments to generate and include \GP{}
+% figures the \EGP{}-package provides commands to use \GP{} for the 
+% calculation of arbitrary arithmetic expressions. Since the \GP{}-|plot|
+% command is used for this feature every expression that is accepted by this
+% command is possible.  But this may also lead to unexpected results if the
+% expression contains the variable~$x$ which is used as the independent
+% variable of the \GP{}-|plot| command. As stated
+% above~(cf.~p.~\pageref{sec:intro}) the UN*X text utils are used for the
+% implementation and so the calculation commands can only be used on systems
+% where these are installed.
+%
+% \DescribeMacro{\egpcalc}
+% Let \GP{} calculate the value of a \meta{\GP-expression}. The result is written to a
+% file. 
+% The optional argument assigns a name to be used with |\egpuseval{|\meta{name}|}|.
+% \begin{quote}
+% \begin{flushleft}
+%   |\egpcalc[|\meta{name}|]{|\meta{\GP-expression}|}|\\
+% \end{flushleft}
+% \end{quote}
+%
+% \DescribeMacro{\egpuseval}
+% Insert a previously defined calculation result. 
+%
+% \DescribeMacro{\egpshowval}
+% Does the same as the |\egpcalc|-command but additionally the result is placed 
+% in the output at the position of the |\egpshowval|-command.
+%
+% \DescribeMacro{\egpassign}
+% The first argument is the name of a \meta{\GP-variable} or \meta{\GP-user
+% function} which is assigned the second argument which is a
+% \meta{\GP-expression}. The result is placed in the output as for the
+% |\egpshowval| command. 
+% 
+% \subsection{Procedure}
+% \label{sec:procedure}
+%
+% After \LaTeX{} has done it's job for the first time you have to invoke \GP{}
+% on the generated file~(default: |\jobname.gp|). Then another \LaTeX{} run is
+% necessary to include the figures and the results into the output.
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \subsection{Examples}
+% \label{sec:examples}
+%
+% For a simple example, let's draw the function
+% $f(x)=\sin({\sqrt{x^2+y^2}})/\sqrt{x^2+y^2}$.
+%    \begin{macrocode}
+%<*sample>
+\begin{egpfile}

+\end{egpx}
+\end{center}
+%
+% Additionally we define a figure that will not be shown here but at the place
+% of the appropriate |\egpuse| command.
+% 
+%    \begin{macrocode}

+            2*sin(u)*sin(v/2)+sin(2*u)*cos(v/2)
+\end{egpdef}
+%    \end{macrocode}
+\begin{egpdef}{kleinbottle}
+     set hidden3d
+     set parametric
+     set nokey
+     set nogrid
+     set noborder
+     set noxtics
+     set noytics
+     set noztics
+     set xrange [-10:10]
+     set yrange [-10:10]
+     set zrange [-3:3]
+     set urange [0:2*pi]
+     set vrange [0:2*pi]
+     set isosamples 39,60
+     set view 60,120
+     set title "Klein bottle"
+     splot  (2*sin(u)*cos(v/2)-sin(2*u)*sin(v/2)+8)*cos(v), \
+            (2*sin(u)*cos(v/2)-sin(2*u)*sin(v/2)+8)*sin(v), \
+            2*sin(u)*sin(v/2)+sin(2*u)*cos(v/2)
+\end{egpdef}
+%
+% Since we have given a name to each diagram, we can now use them with 
+%    \begin{macrocode}
+\begin{figure}
+  \begin{center}
+     \fbox{\egpuse[scale=0.4]{sombrero}}
+     \fbox{\egpuse[scale=0.4]{kleinbottle}}
+  \caption{Two examples taken from the \GP{} demo}\label{fig:demo}
+  \end{center}
+\end{figure}
+%    \end{macrocode}
+%
+% and the result is shown in figure~\ref{fig:demo}.
+%
+\begin{figure}
+  \begin{center}
+     \fbox{\egpuse[scale=0.4]{sombrero}}
+     \fbox{\egpuse[scale=0.4]{kleinbottle}}
+  \caption{Two examples taken from the \GP{} demo}\label{fig:demo}
+  \end{center}
+\end{figure}
+%
+% To calculate the value of $f(\pi/4)$ we issue the command
+%
+% $f(\pi/4)=\egpshowval[sin_quarter_pi]{sin(pi/4)}$
+%    \begin{macrocode}
+$f(\pi/4)=\egpshowval[sin_quarter_pi]{sin(pi/4)}$

+% \section{Acknowledgements}
+% I would like to thank Thorsten Ohl for submitting the \EMP{} package to CTAN.
+% By using it as a template I managed it to adapt the idea of integrating the
+% image generating commands into \LaTeX{} for \GP{}. A lot of code of the
+% \EMP{} package was reused with only marginal changes.  This is also caused by
+% the fact that I am far away from understanding all of the code of \EMP{}.
+%
+% \section{Todo}
+% In additon to optimising \EGP{} it would be nice if the features that are
+% provided through the use of UN*X text utils were implemented in
+% \TeX{}/\LaTeX{}. Another interesting feature to implement in following
+% versions of \EGP{} is the possibility to use other output formats 
+% provided by \GP{}, especially the |pslatex| and |pstricks| terminals but also
+% the |png| terminal for inclusion into PDF could be useful.
